  • Receipt of systemic glucocorticoids (e.g., prednisone ≥ 10 mg/day for more than 14 consecutive days) within 30 days prior to the first dose of study vaccine, or any other cytotoxic, immunosuppressive or immune-modifying drugs within 365 days of study enrollment. Topical, intra-articularly injected, or inhaled glucocorticoids, topical calcineurin inhibitors or imiquimod are allowed.
  • Any significant disorder of coagulation or treatment with warfarin derivatives or heparin. Persons receiving individual doses of low molecular weight heparin outside of 24 hours prior to vaccination are eligible.

  • An acute evolving neurological disorder or Guillain Barré Syndrome within 42 days of receipt of prior seasonal or pandemic influenza vaccine.
  • Administration of an inactive vaccine within 14 days or of a live attenuated vaccine within 30 days before the first dose of study vaccine/product.
  • Planned administration of any vaccine other than the study vaccine/product before blood sampling at the Day 42 visit.
  • Previous administration of any H9 vaccine or physician-confirmed H9 disease.
  • Use of any investigational or non-registered product other than the study vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period.
  • Receipt of any immunoglobulins and/or any blood products within 90 days before study enrolment or planned administration of any of these products during the study period.
  • Any known or suspected allergy to any constituent of influenza vaccines or component used in the manufacturing process of the study vaccine including a history of anaphylactic-type reaction to consumption of eggs; or a history of severe adverse reaction to a previous influenza vaccine.
  • Known pregnancy or a positive urine beta-human chorionic gonadotropin (β-hCG) test result before the first vaccination.
  • Lactating or nursing women.
  • Any condition which, in the opinion of the investigator, prevents the subject from participating in the study.
